7 . From the moment you open your eyes in the morning,     you can feel sweat (汗水)running down your body,     even if you’re barely moving at all. That’s what most people in China felt like this summer. In fact, the entire northern hemisphere(半球 )saw high temperatures in July. The Arctic Circle(北极圈) was no exception(例外). Temperatures in the city of Norilsk, which is in the Arctic Circle, reached a record high of 32 ℃,   The Atlantic reported. Temperatures there are usually just 10 ℃ at this time of the year.

The heat wave in the Arctic is mainly a long-term result of global warming, according to the Chinese Academy of Meteorological Sciences. In fact, while the whole world is getting warmer, the Arctic is warming twice as fast as the rest of the planet. This is called the polar amplification effect(极地放大效应).

The most direct impact(影响) of Arctic warming is the melting of Arctic ice. According to NASA,     Arctic sea ice is now disappearing at a rate of 13. 2 percent every 10 years. NASA said that if this continues,     the Arctic will have no ice by the year 2040.   This has put some Arctic animals, like polar bears, in danger. The ice that the bears live on has shrunk(缩小), the Toronto Star reported.

Melting ice can also cause sea levels to rise in the long term. Since 1993, sea levels have risen at a rate of 3. 2 cm every 10 years, the Guardian reported. Some countries, such as Tuvalu(图瓦卢) in the South Pacific Ocean and Maldives(马尔代夫) in the Indian Ocean, are at risk of disappearing into the sea.

10 . China is a big country, and there is no simple answer to the question “When is the best time to visit China? ” There are two best times to visit China, depending on your preference.

October

Things to do: hike on the Great Wall, photography tour

Places to visit: Beijing, Xi’an, Shanghai, Guilin,Jiuzhaigou, Chengdu

The best time to go to China is early autumn (October).

Most of China has warm temperatures, and the summer rains have stopped (apart from around HongKong and Sanya) so it’s pretty dry. The autumnn colours are also amazing. It is quiet at tourist attractions for most of the month, as the summer holiday travel crowds have gone. But try to avoid October 1 st -7 th, which is the Chinese National Day holiday, as attractions, transport and hotels are packed with Chinese tourists and prices go up a lot.

Late Spring (April to May)

Things to do: appreciate flowers, Li River cruise, ethnic festivals

Places to visit: Beijing, Xi’an, Guilin, Huangshan, GuiZhou, Zhangjiajie

The second-best time to travel to China is probably in April and May, when the flowers are in bloom and the temperatures are warming up. In late spring, temperatures across China are getting into the 20s (℃), except the extreme northwest and northeast. While the North of China is still dry, the summer rains have already begun in the South. This could actually improve the view in the form of mountain fog in mountainous areas like the Li River and the Yellow Mountains.

Ethnic festivals in GuiZhou are concentrated in April and May, such as the Sisters’ Meal Festival. If you are interested in Miao and Dong ethnic cultures, this is a good time to visit.

Travel prices are average: cheaper than June to October, but more expensive than the lower season from November to March.
